Apolipoprotein A-I (Apo A-I)

The Apolipoprotein A-I (Apo A-I) blood test measures the level of Apolipoprotein A-I, which is a protein component of high-density lipoprotein (HDL) cholesterol. Apo A-I plays a key role in the transport and metabolism of cholesterol in the body.

Sample Type: The test requires a small blood sample, typically obtained by drawing blood from a vein in your arm using a needle.

Normal Range: The normal range for Apolipoprotein A-I levels can vary depending on the specific laboratory and the reference values they use. Generally, the normal range is around 110 to 170 milligrams per deciliter (mg/dL).

The Apolipoprotein A-I blood test is primarily used to assess the risk of cardiovascular disease. High levels of Apo A-I are associated with a lower risk of heart disease, while low levels may indicate an increased risk.

Apolipoprotein A-I is the main protein component of HDL cholesterol, often referred to as “good cholesterol.” HDL cholesterol helps remove excess cholesterol from the bloodstream, preventing it from depositing on artery walls and forming plaques.

The Apolipoprotein A-I test is usually ordered along with other lipid profile tests, such as total cholesterol, LDL cholesterol, and triglycerides, to provide a comprehensive assessment of a person’s cardiovascular risk profile.

If your Apolipoprotein A-I levels are outside the normal range, it’s important to consult with a healthcare professional for proper interpretation of your test results and to discuss any necessary lifestyle changes, medications, or further diagnostic tests that may be needed to manage your cardiovascular risk. Additionally, it’s essential to consider the results in the context of other risk factors and medical history to make informed decisions about your cardiovascular health.
